An 8th grade class develops a linear model that predicts the number of cheerios (a small round cereal) that fit on the circumference of a plate by using the diameter in inches.Their
Model is cheerios = 0.56 + 5.11(diameter).
If the diameter is increased from 4 inches to 14 inches, the predicted number of cheerios will
Increase by about…
A)72
B)51
C)10
D)21
E)none of these above

Question

Quizplus · Accepted Answer

The increase in the number of cheerios is calculated by the change in diameter multiplied by the slope of the linear model: 5.11 * (14 - 4) = 5.11 * 10 = 51.
